<p>So a friend was just asking me whether if an application (for an internship) says “the deadline is February 20, 2009”, does that mean its due at the beginning or end of the day?</p>
<p>Often, BUT NOT ALWAYS, it means the application has to be postmarked no later than the 20th. Sometimes it may mean the applications has to be received by that date. Your friend should call to check.</p>
